Hey guys - I have been following this board for many a years - I have had a few cars - 2000 M5, then a 2002 M5, then 2005 e55, back to a 2006 M3 - now currently a 2006 M5.

Let me first say that the knowledge that many of you have is truly amazing - I learn something new everyday.

I know that some love Dinan products - while others have differing thoughts. I just simply want to share my 2 thoughts.

Let me say that while I loved both of my e39 M5's dearly - the current e60 M5 is the best car - for me - I have ever owned. I did have the Dinan stage 3 suspensions on both of those cars and thought it was a tremendous improvement over stock.

About a month ago - I had my local BMW dealer - while replacing the SMG pump - recall issue (?) the Dinan stage 1 software. I could probably convince myself that it made a big difference - but maybe it did - and maybe it did not - -but butt dyno said it was nice and smooth and made me at least happy.

Over the last few days I had both the Dinan stage 2 suspension and Dinan exhaust installed. It is somewhat like owning a new car. In my humble opinion - and again - I am a lowly dentist - no car expert - that is the best money one could spend on a mod - it rides so beautifully - so smooth and flat - not jarring, nor ragged- just precise. I am very happy about that one.

I was very nervous about the exhaust - I was looking for sophistication and a modest increase in level of sound - but not necessarily "noise". I believe that is what I have found.

First of all - it looks fantastic - just the right size - beautiful fit and look to everything. At idle the car sounds a bit more grumbly than stock- but nothing terrible. It seems that between 4000-6000 RPM is where this thing really screams - I personally think the sound is wonderful. The perfect balance between a bit of beautiful melodious v10 (if there is such a thing with a 10 cylinder) and "noise".

Right now - I could not be happier - living outside of Chicago - in a few months -the summers will come off and the winter wheels will go on. Interesting to see if I like the suspension changes as much then. It was the best money I spent on the e39 M5's - and so far the best perhaps I have spent on the e60 M5.

Just my 2 cents.

I think for sure I will go for the cold air intake once Dinan release's it - in for a penny - in for a pound.

I know - many will have a different opinion than mine - and I truly respect that. But at least for what my limited knowledge and experience is - I could not be happier.

Oh - btw - my Blinder M45 came today and will be installed Tuesday by the same guys who hardwired my V1.

I would be happy to to the best I can to answer any questions anyone has about my experiences.

Thanks so much for all who contribute to this board - you have all helped me countless times

Your modifications sound impressive, and it's great that you are so pleased with them. I am debating the Dinan Stage 2 vs the H&R Springs. Please post some pictures of how your M looks with the lowered suspension, and, if possible, a video of how it now sounds!

Thanks for all the positive responses - I will try and post some pics over the weekend.

I did have one semi-interesting thought - when I first had the stage one software installed - I somewhat had to convince myself that it was worth the $1000. But now with a few mods installed - i am firmly of the belief that the sum of the parts is greater than the individual ones. But, again, it may just me convincing myself that it was all worth it -

I would say without any conviction - anyone who is even remotely considering the Dinan suspension upgrade - do it. I really like the non-warranty issue - so I cannot speak of some of the other kits available - but this should be a no brainer for anyone who is even thinking about it - just love it!

I watched the Dinan interview last night from Gustav - just cannot wait for the CAI - and the new cams - damn - now I should probably have to get the throttle bodies installed as well - jesus - this is a terrible addiction!
